分别以2种硝基羧酸配体EBNB(1,2-二(3-硝基苯甲酸)-乙烯)和NPA(3-硝基邻苯二甲酸)与BPY(4,4′-联吡啶)及金属锌反应,配位溶剂热法合成了2种具有硝基基团修饰的二核金属簇为基本构筑单元的金属有机框架化合物[Zn2(EBNB)2(BPY)2·2H2O]n(1)和[Zn2(NPA)2(BPY)2·H2O]n(2)。通过X-射线单晶衍射法测定了2种配合物的结构,其中配合物1属于三斜晶系,P1空间群,a=0.818 62(9)nm,b=1.142 20(14)nm,c=1.428 63(17)nm,α=96.803 0(10)°,β=93.045 0(10)°,γ=102.472(2)°,V=1.290 8(3)nm3,Z=2,Mr=595.81,Dc=1.533 g·cm-3,μ=1.01 mm-1,F(000)=608,T=293(2)K;配合物2属于三斜晶系,P1空间群,a=1.154 06(14)nm,b=1.190 86(16)nm,c=1.459 52(19)nm,α=98.029(1)°,β=98.749(1)°,γ=113.579(2)°,V=1.771 9(4)nm3,Z=2,Mr=879.35,Dc=1.648 g·cm-3,μ=1.43 mm-1,F(000)=892,T=293(2)K。同时也对2种配合物的发光性能进行了测试,测试结果表明2种配合物具有较好的荧光性能。
Two kinds of nitrobenzoic acid ligand EBNB (1,2-bis (3-nitrobenzoic acid) -ethylene) and NPA (3-nitrophthalic acid) ) And metal zinc reaction, two kinds of metal-organic framework compounds [Zn2 (EBNB) 2 (BPY) 2 · 2H2O] n 1) and [Zn2 (NPA) 2 (BPY) 2 .H2O] n (2). The structures of two complexes were determined by X-ray single crystal diffraction. Among them, complex 1 belongs to the triclinic system, space group P1, a = 0.818 62 (9) nm and b = 1.142 20 = 1.428 63 (17) nm, α = 96.803 0 (10) °, β = 93.045 0 (10) °, γ = 102.472 (2) °, V = 1.290 8 (3) nm3, Z = 2, Mr = 595.81 , D = 1.533 g · cm-3, μ = 1.01 mm-1, F (000) = 608, and T = 293 (2) K. Complex 2 belongs to triclinic system with P1 space group, a = 1.154 06 ( 14.972 nm, c = 1.459 52 (19) nm, α = 98.029 (1) °, β = 98.749 (1) °, γ = 113.579 (2) °, V = 1.771 9 (4) nm3, Z = 2, Mr = 879.35, Dc = 1.648 g · cm-3, μ = 1.43 mm-1, F (000) = 892, T = 293 (2) K. The luminescent properties of the two complexes were also tested. The results show that the two complexes have good fluorescence properties.
